[0026] The working principle of a rotatable operating platform for welding elevator parts provided by the utility model is as follows:

[0027] When the rotatable operating platform is used to weld elevator accessories, the power is first turned on, and then according to actual needs, the rotation of the servo motor 11 is controlled to rotate the drive shaft 12, thereby driving the rotation of the lower turntable 2 and the upper turntable 4. At the same time, the extension and retraction of the electric cylinder 31 can adjust the inclination angle of the lower turntable 2 to meet the needs of different welding angles.

[0028] After the inclination of the upper turntable 4 is adjusted, the operator can adjust the height of the upper turntable 4 by controlling the extension and retraction of the electric cylinder 2 52 as needed to make the fixing pin 2 41 slide in the guide opening. This design enables the operating platform to adapt to the welding requirements of elevator parts at different heights and angles, thereby improving the flexibility and convenience of operation.

[0029] When the elevator parts are placed on the placement seat 22, the operator can rotate the handle 25 to rotate the toothed disc 24, thereby driving the multiple gears 23 and the rotating shaft 21 to rotate synchronously, thereby realizing the rotation of the placement seat 22. This design allows the operator to easily adjust the welding position of the elevator parts, thereby improving the welding efficiency.

[0030] At the same time, when the upper turntable 4 needs to be pressed and fixed, the operator can control the extension and contraction of the electric cylinder 2 52 to move the upper turntable 4 toward the lower turntable 2. At this time, the multiple slide bars 42 will push the pressing block 43 to press and fix the elevator parts, ensuring that the elevator parts will not shift during the welding process.

[0031] During the welding process, the operator can adjust the inclination and height of the upper turntable 4 and the lower turntable 2 as needed to meet different welding requirements. At the same time, the operating platform also has the advantages of easy operation, flexible adjustment, strong stability, etc., which can effectively improve the efficiency and quality of elevator parts welding.

[0032] Compared with the related art, the rotatable operating platform for welding elevator parts provided by the utility model has the following beneficial effects:

[0033] The utility model provides a rotatable operating platform for welding elevator accessories. Through the inclination and height adjustable design of the upper turntable 4 and the lower turntable 2, the operator can easily adjust the welding angle and position according to actual needs, which greatly reduces the difficulty of adjusting the welding operating platform and the work intensity of the operator. In addition, the arrangement of the toothed disc 24, the gear 23 and the handle 25 allows the operator to manually control the placement seat 22 to rotate, further improving the flexibility and convenience of operation. At the same time, the design of the stop block 44, the slide bar 42, the pressure block 43 and the spring 45 cooperating to press and fix ensures the stability and reliability of the elevator accessories during the welding process, effectively avoids the displacement problem that may occur during the welding process, and improves the welding quality and efficiency.
